Pattern block play! #21CenturyPB #iTeachMath
The main image in the top left shows a radial design created with 21st Century Pattern Blocks. It was built by arranging six regular hexagons around a central hexagon. All seven hexagons share the same composition and have 4” sides. The first image along the bottom shows a scaled-up kite which is used to create the regular hexagon (with 4” sides) shown in the second image. The kite is made of 1 teal kite, 1 gray dart, 2 green triangles, and 4 pink triangles. The three images on the right show the progression of the design.

Did you know completing the square literally means to complete the square? I didn't when I was in high school and that would've made it so much easier.

Just arrived in Atlanta with these new shoes that I designed using Tile Farm studio. The tessellation on them is related to the truncated squares Archimedean tiling. If you come by the Tile Farm booth at @nctm.org this week I’ll show you how I made them!

From #RaceToNowhere to #CountedOutDoc, one thread connects them all: how belonging and self-belief shape mental health.

On #WorldMentalHealthDay, let’s design systems that nurture confidence, curiosity, and connection so no one feels “counted out.” 💚

This graphic novel is astonishingly original, brilliant, and a joy to read - it actually illuminated my understanding of the original Beowulf. You should get it!

Looking back at some of the shapes and designs from my pattern block play in September! #21CenturyPB #iTeachMath
This image shows pattern block designs arranged in a 4 by 4 grid, with the center four squares merged to highlight a larger design. It features 13 unique dodecagons from September, each created by arranging six rectangles and six equilateral triangles around a central hexagon.
